[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figures 1-2 This utility model provides a snap ring feeding device, including a snap ring guide cylinder 1, a conveyor belt 2 arranged in contact with the lower part of the snap ring guide cylinder 1, through grooves 3 spaced apart on the conveyor belt 2, snap ring receiving platforms 4 formed on both sides of the through grooves 3 to receive snap rings, and a snap ring feeding mechanism for transferring snap rings arranged on the outer side of the snap ring guide cylinder 1. The feeding mechanism includes a first cylinder 5, a second cylinder 6, a distance shortening rod 7 and a snap ring lifting rod 8. The first cylinder 5 is arranged on the outer side of the snap ring guide cylinder 1, and the second cylinder 6 is fixedly installed at the inner rod end of the first cylinder 5. The second cylinders 6 are symmetrically arranged, and the inner rod of the second cylinder 6 is fixedly connected to the distance shortening rod 7. The snap ring lifting rod 8 is fixedly installed below the distance shortening rod 7.

[0026] Specifically, the distance between the bottom of the snap ring receiving platform 4 and the upper side of the conveyor belt 2 is the same as the thickness of the snap ring, and it can support a number of snap rings.

[0027] Specifically, the width of the slot 3 is greater than the diameter of the retaining spring, which facilitates the up and down movement of the retaining spring lifting rod 8.

[0028] Specifically, such as Figure 1 As shown, the upper part of the snap ring guide cylinder 1 is arc-shaped and open, which facilitates the neat stacking of snap rings.

[0029] Specifically, such as Figure 2 As shown, the distance shortening rod 7 has a concave bent structure, which facilitates the installation of the second cylinder 6.

[0030] Specifically, such as Figure 2 As shown, the lower part of the retaining spring lifting rod 8 is an outwardly curved arc shape, which prevents the retaining spring from falling off after it is fixed.

[0031] Working principle:

[0032] The snap rings in the vibratory feeder slide down the guide rod into the snap ring guide cylinder 1, and are then stacked inside the snap ring guide cylinder 1. When the conveyor belt 2 passes through the snap ring guide cylinder 1, the snap rings fall to the snap ring receiving platform 4 and are carried by the conveyor belt 2 to the feeding mechanism. At this time, the first cylinder 5 descends and the second cylinder 6 retracts, moving the snap ring lifting rod 8 to the inside of the snap ring. Then the second cylinder 6 extends, and the snap ring lifting rod 8 fixes the snap ring. The first cylinder 5 retracts, bringing the snap ring up. Once the first cylinder 5 is fixed to the drive device, the feeding mechanism is moved to the snap ring sleeve position. At this time, the first cylinder 5 descends again, and the second cylinder 6 retracts, completing the snap ring detachment and unsleeving.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
